Thanks; but let me clarify - I was in no way saying emotion made her weak. In Humpty Dumpty, Cuddy getting emotionally involved made sense, because she knew the patient. But it was unprofessional of her to stay on the case. Same when she went crazy over the pregnant woman. Her inability to realize she's not being objective is probably why she sucks as a doctor. (Worse, the show rewards Cuddy for this behavior in S3.)

It doesn't bother me that she is a mediocre docter, because she is a good boss [...] I think that the writers have given her more depth...
I had no problem with that - when she was actually a good boss. But Cuddy isn't even good at that anymore. And despite my complaint about her being softened in S2, I think that's where the majority of her character development was, whereas now she doesn't have any. (What have we learned about her in the past two seasons besides she can't get a date?)
